Revision 85eb4f303f4fc9eb8edfd9be0f6f67d435af9972 authored by ha1215 on 23 April 2024, 01:54:36 UTC, committed by Tomas Mraz on 09 September 2024, 07:23:38 UTC
The possessive form of "Windows" has been updated from "Windows's" to "Windows'". The function call "a poll(2) call" has been specified as "a poll(2) system call" for clarity. The phrase "and supposed" has been corrected to "and was supposed" to improve sentence structure. The phrase "However Microsoft has" now includes a comma, revised to "However, Microsoft has" to enhance readability. The statement "Supporting these is a pain" has been adjusted to "Supporting these can be a pain" to better convey potential variability in user experience.
